Area police departments are warning the public and advising parents to be aware of marijuana candy.

A post on the Limerick Police Department’s Facebook page, warned that candy made with finely ground marijuana had been purchased in Upper Darby recently and could be mistaken for green Jolly Ranchers or other clear colored candy.

“Weed Candy is the result of a fine grinding of marijuana and a mixing process with glucose based liquids that are then allowed to harden into a rock like candy. More advanced preparation can make the illegal substance appear like traditional candies. Parents should be suspicious of unwrapped or re-wrapped candy,” read the police department’s notice on Facebook.

A report on WFMZ said a mother in Upper Merion gave a batch to the local police department to be tested and the candy came back positive for marijuana.
